“…We will investigate the observational consequences in the rest of the paper, and in particular in Section VI. Our results for the standard four shapes are also in excellent agreement with previous studies [61,70], confirming the validity of our numerical computations.…”

We investigate how well future large-scale radio surveys could measure different shapes of primordial non-Gaussianity; in particular we focus on angle-dependent non-Gaussianity arising from primordial anisotropic sources, whose bispectrum has an angle dependence between the three wavevectors that is characterized by Legendre polynomials PL and expansion coefficients cL. We provide forecasts for measurements of galaxy power spectrum, finding that Large-Scale Structure (LSS) data could allow measurements of primordial non-Gaussianity that would be competitive with, or improve upon, current constraints set by CMB experiments, for all the shapes considered. We argue that the best constraints will come from the possibility to assign redshift information to radio galaxy surveys, and investigate a few possible scenarios for the EMU and SKA surveys. A realistic (futuristic) modeling could provide constraints of fNL loc≈1(0.5) for the local shape, fNL of O(10)(O(1)) for the orthogonal, equilateral and folded shapes, and cL=1≈80(2), cL=2≈400(10) for angle-dependent non-Gaussianity showing that only futuristic galaxy surveys will be able to set strong constraints on these models. Nevertheless, the more futuristic forecasts show the potential of LSS analyses to considerably improve current constraints on non-Gaussianity, and so on models of the primordial Universe. Finally, we find the minimum requirements that would be needed to reach σ(cL=1)=10, which can be considered as a typical (lower) value predicted by some (inflationary) models. © 201

“…Measurements of non-Gaussianity have been done (and forecasted) for spectroscopic (see e.g. [6,8,45,55,[70][71][72]) and radio continuum surveys (see e.g. [41,42,47,73]).…”

“…These results are in agreement with those found by Diehl et al (1978) amd Manjaya et al (2007), cited that irradiation of globular protein causes formation of protein aggregates which effect on its solubility. Byun and Kang (1994) reported that irradiation of soybean proteins caused decrease in the 7 S and 11 S fractions and corresponding increase in the 2 S and 15 S fractions. Therefore partial degradation of 7 S globulin into 2 S protein and aggregation of 11 S globulin to 15 S component were proposed as result of ionizing radiation.…”

The proteins properties of three oil seeds (soybean, peanut and sesame) were investigated following γ-irradiation (0.0, 0.5, 1.0, 2.0, 3.0, 5.0 and 7.5 KGy). The effect of γ-radiation on total protein solubility, albumin, globulin and SDS-ME fractions were studied using SDS-polyacrylamide gel electrophoresis. The results showed that solubility of total protein were decreased and reached to the maximum decrease using irradiation dose of 7.5 KGy compared to control. The interesting phenomena are that albumin and globulin fractions decreased in its solubility while the SDS-ME fraction increased. These phenomena may be due to the effect of gamma radiation on the protein, which may dissociate this fraction to small subunits, and rearrangement to form a complex protein even high or small molecular weight proteins solubilized only in SDS-ME fraction. The changes in protein profile were depended even on radiation dose and on the nature of oil seeds; soybean, peanut and sesame.

“…Kent et al [24] used DSC as a method to detect irradiated poultry products as irradiation at higher doses significantly changes the thermal properties of the samples. Changes in the values of H was reported by Myung et al [25] for irradiated soya bean proteins and studied the effect of irradiation dosage on T g , T m , and H.…”

Studies were conducted to evaluate the thermal properties of irradiated fluidised bed dried (75 • C, 6 h) mutton using differential scanning calorimetry. The samples were subjected to γ -irradiation at Bhabha Atomic Research Centre (BARC), Mumbai to study the effects of different doses of irradiation (0, 2, and 4 kGy) on the differential scanning calorimetry profile of fluidised bed dried mutton samples prepared with natural antioxidants [MRPs (glucose + lysine 60 mM/2 h), ascorbic acid (500 ppm), and spices (250 mg/100 g of mutton sample)]. The study revealed that the glass transition temperature (T g ) and change in enthalpy ( H) increased significantly (P < 0.05) with irradiation dosage, i.e., 1.97 to 22.30 • C, and 222.5 to 360.70 J/g, respectively. Investigations on isothermal differential scanning calorimetry were carried out to study the crystallization kinetics. Significant increase (p < 0.05) in crystallinity was observed with respect to irradiation dosage. The reconstitution characteristics of the product were also determined and correlated with kinetics of crystallization and irradiation dosage. Thermal studies revealed that irradiation at higher doses significantly changed the thermal and physical properties of the samples.
